The Nike Go FlyEase 'Black' is a groundbreaking hands-free sneaker that comes in three initial color options. The shoe's accessibility is driven by a unique technology called the patent-pending bi-stable hinge. This hinge is secured using a rubber midsole tensioner, which extends from the toe to the back of the heel. When the hinge is open, the insole's back is lifted at about a 30-degree angle, enabling the foot to effortlessly slide in and collapse the hinge. Removing the shoe is just as simple - the wearer can step on the 'kickstand' heel and easily step out.
